Scientists propose new theory of Jupiter’s moon formation

The scientific community has known that Jupiter has four moons since galileo,media reported. These satellites include Ganymede, Ganymede, Ganymede and Ganymede. All four satellites have significant differences, but interestingly, they are all about the same size, about a quarter of the Earth’s radius.

Although they are similar in size, each satellite is very different, like Ganymede, which has significant volcanic activity, Ganymede is covered with ice, Ganymede has a magnetic field, and Ganymede is covered by ancient craters. Perhaps the most interesting of these is Ganymede, which is thought to be one of the most likely places for life beyond Earth in the solar system. Scientists have long wondered how Jupiter’s moons formed, and now researchers at the California Institute of Technology have a new theory.

Using analytical calculations and large-scale computer simulations, the researchers concluded that during the first few million years of solar life, it was surrounded by a disk of protoplanetary gases and dust. Jupiter is formed by a disk nebula and surrounded by a disk-shaped nebula of its moon-made material, called circum-Jovian disc. The disk is supplied by a disk of protoplanets, which transport sits material to Jupiter’s poles and flow along Jupiter’s equatorial surface to Jupiter’s gravitational range.

The new model by Caltech researchers combines the physics of the interaction of dust and gas in circum-Jovian disk. The researchers were able to demonstrate complete offsets of the ice dust particles in a specific size range and the clamping forces and gas that carry them flow outwards. In this way, the disk acts like a giant dust collector, which is rich in ice-cold dust particles, each of which is known to be about 1 mm in size. Eventually, the dust ring became so large that it collapsed under its own weight and created thousands of “satellites” that were cold objects about 100 kilometers in diameter that resembled asteroids.

For thousands of years, these objects coalesced one by one on satellites. The model predicts that Ganymede was the first to form, and that its gravitational effects set off waves in the gaseous material disk that surrounds the planet. The moon moves toward Jupiter until it reaches the inner edge of the disk close to its current orbit. This process began again and brought the birth of Ganymede and Ganymede. The three satellites are locked in the so-called Laplace resonance, one of the most famous features of the satellite’s orbit. The sun’s radiation eventually blew away the remaining gas in the disk. The rest forms Ganymede, but it has no gas to drive toward Jupiter, making it impossible to resonate with other moons.
